Sea Invertebrate Throws Light On Development Of Human Blood And Immune Systems

Sea Invertebrate throws light on development of human blood and immune systems. Botryllus schlosseri a water invertebrate that thrives in underwater colonies reminding fuzzy pinheads clutching to rocks possessed a blood forming system with unreal likeness to humans as per the scientists at Stanford University.

The researchers said that these shallow sea creatures may offer a way to comprehend our own blood-forming system, upgrade our immune operation and discover contemporary immune related tools for biological discovery.

Former postdoctoral scholar Benyamin Rosental said that the mammalian and Botryllus blood-forming arrangement also split innumerable homologous genes inspite the two species are segregated by over 500 million years of evolution.

The researchers secluded the Botryllus stem cells that are the base of its blood and immune system and progenitor cells they render on their path to engendering adult blood and immune cells. Weissman, who also directs the Stanford Institute for Stem Cell Biology and Regenerative Medicine center said that amongst the invertebrates the Botryllus blood stem cells and progenitors are alike vertebrate blood cells so it is probable that they are the broken thread between vertebrates and invertebrates.

Botryllus is a life form with varied queer features. It thrives for most of its life as a free-swimming chordate “tadpole”, vertebrae less animal but with a spinal bundle called notochord. Then it affixes itself to a rock, undergoes transformation to do away with its notochord, tail, body muscles and one of its two brains, and peters down to thrive in colonies with other Botryllus entities on the sub tidal surface.
